Tekton roll pin punches can be used to drive out or insert hollow pins. The long, straight punch is machined to precise tolerances and has a guide ball on the tip to drive out or insert hollow pins without damaging them or the workpiece. Each punch is heat treated to harden and strengthen the tip while maintaining the soft temper of the striking end. The striking end absorbs hammer blows without chipping. Tekton pin punches are made from 5160 high carbon steel and finished with a dry, rust-preventative coating. They're also marked with a high-visibility laser marking. All Tekton punches and chisels are made in the USA.
